Early Origins of the Sline family

The surname Sline was first found in Wales where Robert FitzStephen (d. 1183?), was "one of the original Norman conquerors of Ireland. He was the son of Stephen, constable of Aberteivi (Cardigan), and of Nesta, daughter of Rhys ab Tewdwr, king of South Wales. In 1157, Robert followed Henry II's expedition into North Wales, and narrowly escaped the ambush in which his half-brother, the king's son, was slain. His inheritance included Cardigan,_Ceredigion' target='_blank'>Cardigan and Cemmes, and he became constable of Cardigan town in succession apparently to his father. In November 1166 he was betrayed by his own men into the hands of his cousin, Rhys ab Gruffydd, with whom he was then at war. In the spring of 1169 Fitzstephen, with his half-brother, Maurice Fitzgerald (d. 1176), landed in Ireland at Baganbun or Bannow, near Wexford. They were accompanied by thirty knights, sixty men-at-arms, and three hundred Welsh foot soldiers." 1

William FitzStephen (d. 1190?), was the biographer of Becket, and styled himself the archbishop's 'concivis.' He was in the closest connection with Becket for ten years or more, as his 'clericus et convictor.' 1

Sline Spelling Variations

Multitudes of spelling variations are a hallmark of Anglo Norman names. Most of these names evolved in the 11th and 12th century, in the time after the Normans introduced their own Norman French language into a country where Old and Middle English had no spelling rules and the languages of the court were French and Latin. To make matters worse, medieval scribes spelled words according to sound, so names frequently appeared differently in the various documents in which they were recorded. The name was spelled Fitzstephen, Fitzsteven, Sleyne, Sliney, Sloyan, Sline and many more.

Migration of the Sline family

Because of this political and religious unrest within English society, many people decided to immigrate to the colonies. Families left for Ireland, North America, and Australia in enormous numbers, traveling at high cost in extremely inhospitable conditions. The New World in particular was a desirable destination, but the long voyage caused many to arrive sick and starving. Those who made it, though, were welcomed by opportunities far greater than they had known at home in England. Many of these families went on to make important contributions to the emerging nations of Canada and the United States. Analysis of immigration records indicates that some of the first North American immigrants bore the name Sline or a variant listed above: the name represented in many forms and recorded from the mid 17th century in the great migration from Europe. Migrants settled in the eastern seaboard from Newfoundland, to Maine, to Virginia, the Carolinas, and to the islands..
